In the very recent "Money for Nothing" thread (http://www.piscatorialpursuits.com/forum...tml#Post1019247) I cited information from the 2008 study on the economic value of NT Commercial and Recreational fishing in WA which used 2006 data.

On page 31 of the report it cites for recreational steelhead fishing a net economic value of $51,260,500 and 1,097,000 angler days for an average daily value of $46.72. Again, using the CPI calculator from June 2006 to June 2019 that $46.72 is now $58.98.

On that same page it has data for freshwater salmon fishing of $82,381,300 and 1,763,000 angler days for a daily average of $46.72 and CPI adjustment to $58.98 or the same as for steelhead.

For saltwater salmon fishing $129,419,300 and 2,574,000 angler days for an average daily value of $50.95 adjusted to $64.32. That equates to saltwater salmon fishing being 9% higher in per angler day's economic value than freshwater salmon/steelhead fishing.

So that provides one source of information differentiating the economic value of river fishing versus saltwater fishing for the same salmonids.
